Yes, I know it is still referenced (hence the mention about the docs) and it
appears to be more wrong than I thought. Obviously if you were to specify
anything it should be xbd0a, not wd0a.
That aside, I've never used a 'root=' line except for linux and I've been
tracking xen3 from very early on. I have this tendency to thin down configs
as much as possible and went through all the absolutely required lines from
the get go.
The nbsd/xen domu kernel isn't much different from a normal kernel WRT to
boot. I believe the kernel now accepts a 'root=' parameter but back when I
first started playing with xen3, there was no such thing to my knowledge.
Don't ask me what value the parameter actually needs ...
To my knowledge, the 'root=' line has _always_ been linux specific WRT to xen3
on nbsd.
